Shoulder Season/Mild Winter Apex Puffy

Thanks Todd 🙂

I have a pullover I made back in the day with 3 oz/sq. yd. polarguard 3D (precursor to Climashield, probably not quite as warm per thickness). I have used it on numerous spring Sierra snow camping trips, temps down to the teens fahrenheit, so say -10 celcius. So I would expect the 3.6 climashield to do the trick, the 6 oz will be overkill and very bulky. I sewed mine with differential cut; outer fabric larger than inner. Somewhat complex as regards patterning ( I made my own pattern), but I think it yields a better product, with less overall fabric weight for the same jacket. I find I need lots of pins to deal with sewing insulation to fabric.

Thanks Peter! Great information.

For a differential cut, do you see the insulation to the outer shell? I.e. is the insulation the same size as shell or lining?

I sewed insulation to the lining. And I assembled all the pieces of lining/insulation to each other, and then all the pieces of shell to each other, so that I had essentially two jackets, and then sewed those together only at the cuffs, the bottom, the front zip, and around the face opening for the hood. So there are no sewn through seams anywhere on the body of the garment or in the hood. Another tip is that I found I had to be very careful not to stretch the insulation when laying out the pieces, because then you can end up with pieces of insulation that are smaller than your pieces of fabric, and that is not good because they will return to that smaller size after you sew them to the fabric. better to have the insulation pieces a little bigger than the fabric rather than the other way around.
